easier and run better.
1. Clean area around spark plug.
2. Remove and inspect spark plug.
3. Replace spark plug if electrodes are pitted, burned
or porcelain is cracked. Use the recommended
replacement plug. See Specifications.
4. Check electrode gap with wire feeler gauge and
reset spark plug gap to recommended gap if
necessary (see Specifications).
5. Install spark plug and tighten firmly.
NOTICE You can purchase a new spark plug by

Inspect Muffler and Spark Arrester
Inspect the muffler for cracks, corrosion, or other
damage. Remove the spark arrester, if equipped, and
inspect for damage or carbon blockage. If replacement
parts are required, make sure to use only original
equipment replacement parts.
NOTICE You can purchase a spark arrester by calling
1-888-331-4569.
WARNING Exhaust heat/gases could ignite
combustibles, structures or damage
fuel tank causing a fire, resulting in
death or serious injury.
Contact with muffler area could cause burns
resulting in serious injury.
• DO NOT touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 5 ft. (1.5 m) of clearance on all sides of
pressure washer including overhead.
• It is a violation of California Public Resource Code, Section
4442, to use or operate the engine on any forest-covered,
brush-covered, or grass-covered land unless the exhaust
system is equipped with a spark arrester, as defined in
Section 4442, maintained in effective working order. Other
states or federal jurisdictions may have similar laws.
Contact the original equipment manufacturer, retailer, or
dealer to obtain a spark arrester designed for the exhaust
system installed on this engine.
• Replacement parts must be the same and installed in the
same position as the original parts.
Air Cooling System
Over time debris may accumulate in cylinder cooling
fins and cannot be observed without partial engine
disassembly. We recommend you have a qualified
Sears service dealer clean the cooling system (see
Maintenance Schedule). Equally important is to keep
top of engine free from debris. See Clean Debris.
Carburetor Adjustment
The carburetor on this engine is low emission. It is
equipped with a non-adjustable idle mixture valve.
Top speed has been set at the factory. If adjustment is
required, see an authorized service dealer.
CAUTION Excessively high operating speeds
could result in minor injury.
Excessively low speeds impose a heavy load.
• DO NOT tamper with governor spring, links or other parts to
increase engine speed. Pressure washer supplies correct
rated pressure and flow when running at governed speed.
• DO NOT modify pressure washer in any way.
AFTER EACH USE
Water should not remain in unit for long periods. Sediments
or minerals can deposit on pump parts and "freeze" pump
action. Follow these procedures after every use:
1. Shut OFF engine, turn off water supply, point gun in a
safe direction, press red button and squeeze trigger
to relieve trapped pressure and let engine cool.
WARNING The high pressure stream of water that
this equipment produces could cut through
skin and its underlying tissues, resulting in
serious injury and possible amputation.
Spray gun traps high water pressure, even when
engine is stopped and water is disconnected, which
could result in serious injury.
• Keep high pressure hose connected to pump and spray
gun while system is pressurized.
• ALWAYS point spray gun in safe direction, press red
button and squeeze spray gun trigger to release high
pressure, every time you stop engine.
2. Disconnect hose from spray gun and high pressure
outlet on pump. Drain water from hose, gun, and
spray wand. Use a rag to wipe off the hose.
3. Empty pump of all pumped liquids by pulling recoil
handle about 6 times. This should remove most
liquid in pump.
4. Place the spray gun, and spray wand with spray
tips in the spray gun holder wireform. Hang high
pressure hose with velcro strap on billboard.
5. Store unit in a clean, dry area.
6. If storing for more than 30 days see Long Term
Storage on next page.
WARNING Fuel and its vapors are extremely
flammable and explosive which
could cause burns, fire or explosion
resulting in death or serious injury.
WHEN STORING FUEL OR EQUIPMENT WITH FUEL IN TANK
• Store away from furnaces, stoves, water heaters, clothes
dryers, or other appliances that have pilot light or other
ignition source because they could ignite fuel vapors.
